Wipe down apparatus for stretch wrapping devices

Abstract

A wipe down apparatus for use on web wrapping devices used to unitize a multiple unit wrapped load. The wipe down apparatus includes an extensible wiper support and a wiper element having one or more strips, one of which is double back along a portion of its length to form a load engaging loop. The strips being flexible along focal points when in contact with a load and moving parallel with the load wiping the wrapped load as it passes the wiper support.

Therefore I claim: 
     
       1. A wipe down apparatus for use with stretch wrapping device for wrapping a load with a film web, the wipe down apparatus comprises a wiper support, an engagement arm telescopically extensible from said support, a wiper element secured to said free end of said engagement arm, said wiper element comprising at least one wiper including a pair of unequal length strips, one of said strips double back on a portion of itself forming a loop in spaced relation to the engagement arm, means for securing the unequal free ends of said strip to each other and to one of said strips inwardly from its secured free end, means for securing the abutting ends of said strips to said engagement arm, means for moving said engagement arm and said wiper support in relation to said load and means for cutting said film web within a film plane path. 
     
     
       2. The wipe down apparatus of claim 1 wherein said means for securing the unequal length free ends of said strips comprises a fastener. 
     
     
       3. The wipe down apparatus of claim 1 wherein said means for securing the abutting ends of said strips comprises an elongated support bracket. 
     
     
       4. The wipe down apparatus of claim 1 wherein said means for moving said engagement arm and wiper support comprises pneumatic cylinders controlled by said stretch wrapping device. 
     
     
       5. The wipe down apparatus of claim 1 wherein means for cutting said film web within the film web's path comprises a hot wire assembly positioned on said extensible arm in angular relation to said wiper element. 
     
     
       6. The wipe down apparatus of claim 1 wherein one of said unequal length strips is resiliently stiffer than the other of said strips. 
     
     
       7. A wipe down apparatus for use with a stretch wrapping device for wrapping a load with a film web, the wipe down apparatus comprises a wiper support, an engagement arm telescopically extensible from said support, a wiper element secured to said free end of said engagement arm, said wiper element comprises at least one wiper including a pair of unequal length strips, one of said strips double back on a portion of itself forming a loop in spaced relation to the engagement arm, a stiffening element between said strips, means for securing the unequal free end of said strips to each other and to one of said strips inwardly from its secured end, means for securing the abutting ends of said strips and said stiffening element to said engagement arm, means for moving said engagement arm and said wiper support in relation to said load and means for cutting said film web within a film plane path.
